Quantum-Inspired Optimization over Permutation Groups
Rathi Munukur, Bhaskar Roy Bardhan, Devesh Upadhyay +1
Quantum-inspired optimization (QIO) algorithms are computational techniques that emulate certain quantum mechanical effects on a classical hardware to tackle a class of optimizatio…
Towards the simulation of transition-metal oxides of the cathode battery materials using VQE methods
Marwa H. Farag, Joydip Ghosh
Variational quantum eigensolver (VQE) is a hybrid quantum-classical technique that leverages noisy intermediate scale quantum (NISQ) hardware to obtain the minimum eigenvalue of a…
Quantum control for high-fidelity multi-qubit gates
Raymond J. Spiteri, Marina Schmidt, Joydip Ghosh +2
Quantum control for error correction is critical for the practical use of quantum computers. We address quantum optimal control for single-shot multi-qubit gates by framing as a fe…
Measurement-free implementations of small-scale surface codes for quantum dot qubits
H. Ekmel Ercan, Joydip Ghosh, Daniel Crow +4
The performance of quantum error correction schemes depends sensitively on the physical realizations of the qubits and the implementations of various operations. For example, in qu…
Pulse sequences for suppressing leakage in single-qubit gate operations
Joydip Ghosh, S. N. Coppersmith, Mark Friesen
Many realizations of solid-state qubits involve couplings to leakage states lying outside the computational subspace, posing a threat to high-fidelity quantum gate operations. Miti…
A decoherence-free subspace in a charge quadrupole qubit
Mark Friesen, Joydip Ghosh, M. A. Eriksson +1
Quantum computing promises significant speed-up for certain types of computational problems. However, robust implementations of semiconducting qubits must overcome the effects of c…
